摘要:

通过分析PMVPPD（预测平均投票数预测不满意百分比）热舒适性指标，基于夏季列车内环境参数，计算最舒适热环境下空气温度与乘客新陈代谢率的关系。发现列车内不同新陈代谢率的乘客达到最舒适状态时所需的温度不同。地铁列车采取同车不同温的空调设定模式后乘客的平均不满意率降低。以某市地铁为例，分析了强冷车厢和弱冷车厢不同分布方案的平均不满意率。研究结果表明：列车前3节车厢为强冷车厢、后3节为弱冷车厢时，整车的不满意率平均值最低。

Abstracts:

By analyzing the thermal comfort index of PMV-PPD (predicted mean vote-predicted percentage dissatisfied), based on the train interior environmental parameters in summer, the relationship between air temperature and passenger metabolic rate in the most comfortable thermal environment is obtained. It is found that the temperatures required by passengers with different metabolic rates to reach the most comfortable states are different. The average dissatisfaction rate of passengers decreases after the metro train adopting the air-conditioning setting mode of one train with multiple temperatures. Taking metro in a certain city as an example, the average dissa-tisfaction rate of different distribution schemes of strong and weak cold compartments is analyzed. Results show that the average dissatisfaction rate of the whole train is the lowest when the first three compartments are strong cold and the last three compartments are weak cold.
